Visualizing knowledge awareness support in ubiquitous learning

The aim of this research is to provide the learner with knowledge awareness support according to his current need and location. Therefore, we presented a ubiquitous learning environment in order to support the learners while doing tasks; this environment is called PERKAM (PERsonalized Knowledge Awareness Map). PERKAM allows the learners to share knowledge, interact, collaborate, and to exchange individual experiences. It utilizes ubiquitous technologies to detect the learner's environmental objects and location, and then recommends the best matched educational materials and peer helpers in accordance with the detected objects and the current location. This environment provides the learner with Knowledge Awareness Map, which graphically displays the knowledge awareness support. The experiment and the questionnaire results indicated that Knowledge Awareness Map is helpful to understand the learner's situation and it efficiently visualizes the recommendations.
